The Binks Comet 4/12 pump is part of a low pressure air-assisted airless system that was designed with an air powered 12:1 two-ball piston pump that is capable of producing 0.4 gpm at 60 cycles per min.

Created to apply water-borne and solvent-borne coatings, the pump is specifically designed to spray wood coatings such as stains, lacquers and sealers at fluid outlet pressures from 300 psi up to 1,200 psi. The Comet 4/12 features a balanced fluid section for a steady, even coating flow and a hard chrome coated stainless steel pump rod. The large displacement per stroke allows for reduced pump rod speed and improved durability.
